Application February 11,1955, Serial No. 487,509

2 Claims. (Cl. 4-57) The present invention relates to new and usefulimprovements in toilet flush tanks and has for its primary object toprovide, in a manner as hereinafter set forth, a device of thischaracter comprising a novel combination and arrangement of valveswhereby either a full or partial flush may be had, as desired.

Other objects of the invention are to provide a flush tank of theaforementioned character which will be comparatively simple inconstruction, durable, compact, highly efficient and reliable in use andwhich may be manufactured at low cost.

These, together with other objects and advantages which will becomesubsequently apparent, reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numberals refer to like parts throughout, and in which:

Figure 1 is a view principally in vertical section through a flush tankconstructed in accordance with the present invention; and

Figure 2 is a view in horizontal section, taken substantially on theline 22 of Figure 1.

Referring now to the drawing in detail, it will be seen that referencecharacter 5 designates a tank of suitable material and capacity for thereception of water, as at 6. The tank 5 is provided with the usual watersupply pipe. Depending from the bottom 8 of the tank 5 is a drain oroutlet 9 to be connected in the usual manner with a toilet bowl. Anoverflow pipe 10 communicates with the outlet 9.

Mounted on the lower end portion of the overflow pipe 10 and alsocommunicating with the outlet 9 is a pair of coplanar valve seats 11 and12. Mounted on the overflow pipe 10 at an intermediate point is a pairof guides 13 and 14.

The stem 15 of a full flush bulb valve 16 is operable in the guide 13. Afull flush operating mechanism designated generally by referencecharacter 17 is operatively connected to the stem 15 by means comprisinga link 13.

The stem 19 of a partial flush bulb valve 20 is slidable in the guide14. A partial flush operating mechanism designated generally byreference character 23, which is substantially similar to the mechanism17 and mounted on the opposite end portion of the tank 5, is operativelyconnected to the valve stem 19 by means comprising a link 21. A float 22is adjustably secured on the stem 19 above the guide 14.

It is thought that the operation of the flush tank will be readilyapparent from a consideration of the foregoing. Briefly, when a completeor full flush is desired, the valve 16 is lifted from its seat 11 in theusual manner by the mechanism 17 and the tank 5 is substantiallyemptied. When a partial flush is desired, the valve 20 is lifted fromits seat 12 by the mechanism 23. When this occurs the water flows fromthe tank in an obvious manner. During the initial discharge of thewater, the float 22 assists in supporting the partial flush valve 20 inraised or open position. However, when the falling water level in thetank 5 reaches the float 22, said float follows it downwardly and theweight of said float is sufiicient to close the valve 20 while the tankis still approximately half full.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. In combination, a toilet flush tank having an outlet, a pair ofcoplanar valve seats communicating with the outlet, a full flush valveengageable with one of the seats, a partial flush valve engageable withthe other of said seats, said partial flush valve including a verticallyslidable stem, a float mounted on said stem, and means for independentlyopening the valves.

2. In combination, a toilet flush tank having an outlet, a verticaloverflow pipe in the tank communicating with the outlet, a pair ofcoplanar valve seats on the overflow pipe communicating with the outlet,a pair of guides mounted on said overflow pipe, a full flush valveengageable with one of the seats and including an upstanding stemslidable in one of the guides, means for opening said full flush valve,a partial flush valve engageable with the other seat and including anupstanding stem slidable in the other guide, a float mounted on thesecond-named stem, and means for opening said partial flush valve.
